Area
The perimeter of a polygon is not generally equal to the number of square units contained in its interior, which is the definition of the area of the polygon, not of its perimeter. By coincidence, the area and perimeter of a square four units on each side have the same magnitude, 16, but the perimeter is 16 units and the area is 16 square units .
If its a regular polygon then it is a 60-agon
A regular polygon with 4 sides is a square. The measure of any interior angle of a square is 90 degrees.
square or octagon

interior
If its a regular polygon then it is a 60-agon
A regular polygon with 4 sides is a square. The measure of any interior angle of a square is 90 degrees.
The smallest regular polygon, an equilateral triangle, has interior angles of 60. A square has interior angles of 90. There can't exist a regular polygon with interior angles of 30.
A rectangle (or square).
That is the polygon known as a "triangle".
